Technical Abstract

A liquid crystal display device includes a liquid crystal display panel and a backlight device which supplies light to a back surface of the liquid crystal display panel. The backlight device includes a diffusion plate, a plurality of cold cathode fluorescent lamps, and a reflection plate on which light is reflected. Assuming arrangement intervals of the plurality of cold cathode fluorescent lamps in the direction from a center portion to a peripheral portion as “a”, “b”, “c”, “d”, “e”, and “f” respectively, the plurality of cold cathode fluorescent lamps is arranged to satisfy the relationship of a>b≧c≧d≧e≧f. Such a liquid crystal display device can control the brightness distribution due to the arrangement of the cold cathode fluorescent lamps within the backlight device thus obtaining a high-quality image display without generating brightness irregularities.
